> While trying to use the protocol-smb plugin (which is not part of the Nutch 
> distribution) I realized there are four steps to successfully make use of a 
> protocol plugin:
> 1 - put the artifact into the plugins directory
> 2 - modify Nutch configuration files to allow smb:// urls plus include the 
> plugin to the loaded list
> 3 - extract jcifs.jar and place it on the system classpath
> 4 - run nutch with the correct system property
> While steps 1 and 2 seem obvious, 3 and 4 require knowledge of plugin 
> internals which does not feel right for nutch and plugin users. Even more, 
> the jcifs.jar would exist twice on the classpath and could even cause further 
> problems during runtime.
